Pen-style Radio Ultrasonic High-Temperature Corrosion Detector
Coating thickness: 5 mm
Lift-off distance: 4 mm
Electromagnetic Acoustic Transducer (EMAT), a new technology emerging in the field of non-destructive testing, uses electromagnetic coupling to both generate and detect ultrasonic waves. Compared to conventional ultrasonic testing techniques, EMAT offers several advantages: high precision, no need for coupling agents, non-contact operation, suitability for high-temperature inspections, and ease of exciting various ultrasonic waveforms. As a result, electromagnetic acoustic transducers are increasingly gaining attention and importance in industrial applications.

800°C Heat-Resistant Temperature Probe
Waveforms can be observed directly or using a tablet.
EMAT electromagnetic ultrasonic technology consists of a permanent magnet and a conductor carrying alternating current. As AC energy flows through the non-contact coil, it generates an alternating magnetic field, which induces eddy currents on the surface of the base material. Charged particles moving within this magnetic field experience the Lorentz force, causing them to repeatedly change direction along the surface of the object being inspected. This Lorentz force induces controlled, minute displacements in the microscopic particles of the eddy current region, ultimately generating ultrasonic waves at the material's surface. The rebounded ultrasonic energy is then directly detected by the non-contact coil—via mechanisms such as magnetostriction—and converted into measurable detection signals.
The EM4000 Electromagnetic Ultrasonic Thickness Gauge can wirelessly connect to tablets, smartphones, or other Android devices. It supports A-scan, B-scan, and C-scan modes.
- Simultaneously measure the base material thickness and surface coating thickness by inputting the known sound velocity of the specific material and the real-time temperature.
- Obtain the most accurate value through computational compensation.
- Indirectly determine whether defects are present by displaying waveforms on your own screen or a wireless tablet device.
- Quickly calibrate using a random standard test block—no complicated calibration procedures required.

Frequently Asked Questions
Can't charge the device?
The device may have been left unused for too long, causing the battery to lose charge. You can try charging it for an extended period. If there’s still no response, we recommend sending it in for repair. Also, please use the dedicated charger provided for each device when charging.
Can't connect the thickness gauge's flat plate to the instrument?
First, turn on the tablet’s hotspot and check whether the eight-digit number in the hotspot name matches the eight-digit SN code of the device. If they don’t match, make the necessary adjustments. Then, follow the instructions in the manual to connect the tablet. If you’re still unable to proceed, we recommend contacting customer support for assistance.
How can I fix the issue of fluctuating readings during thickness measurement?
It is recommended to connect the flat plate during the thickness measurement process and observe the waveform. If the waveform appears poor, switch to manual mode for inspection. If no consistent waveform is detected, consider potential material issues or probe damage—replace the probe and try again. If no waveform still appears after replacing the probe, the material itself may be of poor quality, making it unable to generate an effective signal.
